Similarly, it is asked, should a person with TB be isolated?

If you have been diagnosed with contagious tuberculosis (TB), your health care provider may tell you that you need to be on home isolation. Home isolation will help stop the spread of TB to others. Young children and people with weak immune systems are at highest risk for getting sick with TB.

Similarly, what type of isolation is needed for tuberculosis? Airborne precautions help keep staff, visitors, and other people from breathing in these germs and getting sick. Germs that warrant airborne precautions include chickenpox, measles, and tuberculosis (TB) bacteria.

Correspondingly, how long are you contagious with TB after starting treatment?

People with symptomatic TB are contagious until they have taken their TB medications for at least two weeks. After that point, treatment must continue for months, but the infection is no longer contagious.

When can a TB patient be considered noninfectious?

Patients can be considered noninfectious when they meet all of the following three criteria: They have three consecutive negative AFB sputum smears collected in 8- to 24-hour intervals (one should be an early morning specimen); They are compliant with an adequate treatment regimen for two weeks or longer; and.

What happens if I test positive for TB?

A positive test result means only that TB bacteria has been detected. It does not indicate whether the person has active TB or a latent infection. This requires additional testing, such as a chest X-ray and sputum sample, which tests the thick mucus from the lower respiratory tract.
